Summary of shoulder girdle movements during shoulder elevation "Shoulder elevation" or "elevation of the arm" (Smith, Weiss, & Lehmkuhl, 1996, p. 235) refers to a combination of movements that place the glenohumeral joint in either full flexion or abduction. Elevation involves glenohumeral movement in combination with scapulothoracic movement and thoracic extension.
